Answer:
card number 4
{ (2,-3), (3,-1), (3, 1), (4,1), (5,3) }
Answer:
There are 14 board games
Step-by-step explanation:
Firs of all I defined two variables
V= number of videogames
B= number of board games
Then I translate the information into math equations:
V=6B-28 represents the number of video games is 28 less than 6 times the number of board games.
represents the games are 80% video games. The equation is the number of video games divided for the total number of games
The two equation form a lineal equations system. It is rewritten below
V-6B=-28
V-4B=0
The solution for this equations system is
V=56
B=14
Your answer would be: <em>693.</em>
Explanation:
When finding the area in a problem use <em>L×W×H</em>.
That being said, you now have to multiply the <em>L×W×H</em> (7x9x11)
7 × 9 × 11 = <em>693</em>
So the answer would be <em>693</em> because, if you are finding an area you use <em>L×W×H</em> to find your area.

The value of x from the given equation is -2
<h3>Equations and expressions</h3>
Equations are expressions separated by an equal sign.
Given the expression
x/2 - (5x-3)/12 = 1/3 x - 0.75
Find the LCM
6x-(5x-3)/12 = 1/3 x - 0.75
(x+3)/12 = 1/3 x - 0.75
(x+3)/12 - x/3 = -0.75
(x+3-4x)/12 = 0.75
-3x +3 = 9
Subtract 3 from both sides
-3x = 9 - 3
-3x = 6
x = -2
Hence the value of x from the given equation is -2
